Tesla CEO Elon Musk appeared to poke fun at Bill Gates on Thursday after the Microsoft founder claimed that clean hydrogen energy could zero out emissions and help tackle climate change.
Because its conversion into electricity does not emit greenhouse gases, Hydrogen could potentially serve to meet climate change coals set out by President Joe Biden as well as other world leaders.
However, critics note that while it is a renewable source and has only minimal impact on the environment, it doesn’t come without its risks: it is more flammable than natural gas and its flame is nearly invisible.
‘Cheap, Green Hydrogen Would Be a Massive Breakthrough in Clean Energy’
Hydrogen is also difficult to store, given its low volumetric energy density, and must be compressed into gas or liquid at extremely low temperatures.It also isn’t commercially viable right now.
Gates’ blog post notes that “cheap, green hydrogen would be a massive breakthrough in clean energy” and that “the world already uses 70 million tons of hydrogen each year as a chemical in some manufacturing processes like making fertilizer” of which nearly all is produced from fossil fuels.
“If we make that hydrogen clean, we eliminate the 1.6 percent of global emissions that it is responsible for now,” the billionaire wrote.
However, the process can be expensive and energy-intensive.
“There are four different electrolyzer technologies being developed, and the price of each one needs to go down to make electrolyzed hydrogen cost-competitive,” Gates wrote on his blog.
“Finally, there are reserves of hydrogen in geologic formations around the world, and in theory, geologic hydrogen has the potential to provide a vast supply of affordable, zero-emissions hydrogen,” Gates continued. “Scientists are still in the early stages of researching ways to find and extract geologic hydrogen from natural reserves.”
‘Load Of Rubbish’
Musk has previously called hydrogen fuel cells “a load of rubbish” and claimed that success with hydrogen fuel cell vehicles is “simply not possible.”This is not the first time that Musk and Gates have appeared to butt heads.
However, the tech billionaire noted: “That’s not his track record.”
